Treatment of first-episode and prodromal signs

outreach to ensure engagement with services, making services ‘youth friendly’ and using a multidisciplinary biopsychosocial approach with emphasis on all aspects of recovery.2 Two systematic reviews have confirmed the relationship between long DUP and poor outcome,3,4 and two large randomized controlled trials (RCTs) have demonstrated the effectiveness of EI services in improving short- to medium-term outcomes in established FE.5–8 Besides facilitating recovery in FEP, EI services can also perform two other functions: treatment of at-risk (prodromal) mental states and early detection of psychosis in the community. In this article, we briefly review the evidence for prodromal intervention and early detection and highlight the principles of effective treatment of FEP.

Abstract The first episode of psychosis is now recognized as a critical period for effective intervention. There is also convincing evidence demonstrating the superiority of specialized early intervention services in improving short- to medium-term outcomes of the first episode of psychosis compared with standard care. There is now a concerted international research and clinical effort into identifying and treating ‘prodromal’ cases of psychosis. In this article, we describe the three different ways that early intervention can treat first-episode and prodromal cases (prodromal intervention, early detection and effective treatment of the first episode), summarizing the evidence for each of these strategies. We also outline the principles and ‘therapeutic ingredients’ of effective treatment of the first episode of psychosis.

Prodromal interventions Most patients who develop psychosis experience a long period of changes in behaviour, mood, cognition and functioning prior to the development of frank psychotic symptoms.9,10 Attenuated (subthreshold) psychotic symptoms and transient episodes of true psychosis that remit spontaneously (so-called BLIPS) are also common in the prodrome.11 However, prodromal symptoms are non-specific and have low predictive power in identifying true psychosis. Hence, the term ‘at-risk mental states’ is now commonly used instead of prodrome.12 The PACE (Personal Assessment and Crisis Evaluation) Clinic in Melbourne, Australia, has developed ‘ultra-high-risk’ criteria9 with 35–40% of those meeting these criteria developing a psychotic disorder within 12 months.13,14 The benefits of intervention at that early stage still remain unclear, and arguments have been made both for and against intervening in this group. Critics argue that lack of robust evidence for efficacy of prodromal interventions and the risk of stigmatizing and unnecessarily treating ‘false positives’ outweigh any putative advantages.15 Supporters claim that prodromal cases are already ‘help seeking’; therefore, ‘targeted’ rather than universal preventive strategies using ‘safe’ treatments such as low-dose antipsychotics and cognitive–behavioural therapy (CBT) are ethically and scientifically justified.16 Emerging evidence that brain changes may predate the onset of frank psychotic symptoms17 further strengthen the case for intervention in high-risk mental states. Although results are not conclusive, some evidence has emerged suggesting that intervention in high-risk mental states may delay, if not prevent, the onset of psychosis.18–20 Small sample sizes and lack of clarity about the relative contributions of medication and CBT in some trials suggest that it may be too early to start prodromal services in routine psychiatric care. High-risk/prodromal interventions continue to be an ethically challenging and clinically contentious area requiring further high-quality and methodologically robust research, and are therefore best provided in specialist centres.

Three important changes in mental health care provision have revolutionized the treatment of first-episode psychosis (FEP). These include evidence that the early years of emerging psychosis are critical in improving outcomes; the availability of second-generation antipsychotics; and the provision of care through specialized early intervention (EI) services, allowing the therapeutic pessimism associated with a diagnosis of psychosis to be replaced by cautious optimism. Although there was some early scepticism about the need for specialist services to provide care in FEP, evidence accumulated in the last decade has convincingly demonstrated the superiority of EI services in treating FEP compared with standard mental health care. Several EI models have been developed in the past two decades in Australia, New Zealand, Europe and North America.1 Despite differences in local mental health economies, EI services share certain common characteristics of ideology and function, such as ensuring a minimal delay between the emergence of psychosis and the start of effective treatment (duration of untreated psychosis; DUP), proactive

­ sychosis, problems also occur within mental health services, p whereby individuals who develop psychosis while engaged with mental health services have delayed initiation of treatment for psychosis.21 Since long DUP is related to poor outcome, several strategies have been suggested to ensure earlier detection of cases in the community, including anti-stigma and community education campaigns, training of general practitioners and other individuals from key agencies (i.e. educational authorities, youth services and young offender programmes), information leaflets about local EI services, well-defined and well-publicized ­pathways into care and a proactive approach in suspected cases. There is some evidence that DUP can be reduced at a community level through intensive public education campaigns and provision of early detection teams.22,23 However, the effect of the education campaign may be temporary, with loss of any reduction in DUP when such campaigns are stopped.22 A community education programme in Canada24 found no significant reduction in DUP, and another study found that such campaigns manage to bring into treatment only those individuals with long DUPs who have previously been undetected.25

Principles of early intervention in psychosis • Reduce the time between onset of psychotic symptoms and initiation of effective treatment once the patient has been referred • Accelerate remission through effective biological and psychosocial interventions • Minimize an individual’s adverse reactions to the experience of psychosis • Maximize social and vocational functioning • Promote recovery during the early phase of the illness • Prevent relapse and treatment resistance • Develop meaningful therapeutic engagement early in the course of the disorder based on assertive outreach principles • Provide comprehensive assessment, treatment and rehabilitation in the least restrictive setting • Focus on carers’ needs and involve the family in a therapeutic alliance • Provide and run support groups for patients and carers • Ensure care is transferred thoughtfully and sensitively at the end of the treatment period

Treatment of first episode of psychosis

Table 1

Initial reports from the Early Psychosis Prevention and Intervention Centre (EPPIC) in Melbourne, Australia, suggested that EPPIC patients experienced better outcome with regard to overall quality of life and social functioning, had a lower average length of hospital stay and received lower mean doses of neuroleptics than non-EPPIC patients. The service appeared to be more costeffective than generic services, as the increased community costs of EPPIC were more than covered by reduced inpatient costs.26 Two large RCTs have since confirmed that EI services are more effective in improving short-term outcomes of FEP than standard care. In the UK, the specialized Lambeth Early Onset (LEO) service reduced readmissions and maintained better engagement with patients than standard care. LEO patients also had significantly better functional outcomes and greater adherence to medications at 18 month follow-up, although no marked improvement in symptoms was found.5,6 The OPUS trial in Denmark found similar favourable results for EI services in terms of treatment adherence and service satisfaction over 1 and 2 year follow-up together with a small effect on symptom reduction compared with standard psychiatric treatment.7 The OPUS trial concluded that an intensive EI programme improved clinical outcome after 2 years, but this improvement was not sustainable up to 5 years later.8 Effective treatment of established FEP is phase specific, with treatment strategies and interventions flexibly offered based on differing clinical needs as the disorder progresses. The principles of treatment in the early phases of psychosis are outlined in Table 1, and the therapeutic ingredients of such treatment are shown in Table 2.

t­herapeutic engagement. The best way to achieve this is by offering a multidisciplinary assessment in a low-stigma setting such as at home or at the general practice. The assessment should include, along with a detailed clinical level of functioning, quality of life, social and occupational needs and a detailed risk

Therapeutic ingredients of early intervention • Rapid and assertive response to first service contact with flexibility of appointment times • Primary treatment with atypical antipsychotic medication • Medication review and treatment ‘switching’ for treatmentintolerant or -resistant patients • Care designed to improve medication compliance • Standard side-effect assessment tools used routinely • Care coordinator-led psychosocial interventions such as psychoeducation, compliance therapy, relapse prevention and behavioural family intervention, etc. • Individual psychological treatments including individual cognitive–behavioural therapy • Individual early warnings signs and relapse prevention plan agreed and developed with patients and carers and available on file • Culturally sensitive and appropriate needs assessment • Comprehensive and documented risk assessment • Outreach visits by clinical team members • Care addresses all aspects of daily living • Educational and vocational recovery plan using principles of individual placement and support • Assessment and treatment of comorbidity, especially substance abuse, depression, suicidality and anxiety

The acute phase The key to successful management of the acute phase is to ensure a benign therapeutic start that engenders hope, minimizes stigma, avoids coercion as far as possible and promotes

a­ ssessment. ­Standardized assessment tools are particularly useful since these can be repeated to chart individual progress and also as measures of service evaluation. All patients should be assigned an individual care coordinator responsible for both providing and coordinating care. Individualized care plans need to be drawn up and agreed with the patient so that the care package is seen as consensual rather than coercive. The main aim of treatment in the acute phase is initiating antipsychotics to ensure a rapid symptomatic recovery. While some recent research27,28 shows similar efficacy of first- and second-generation antipsychotics – with the exception of clozapine, which has demonstrable superiority in treating treatment-­resistant cases – the National Institute for Health and Clinical Guidance (NICE) guidelines29 in the UK recommend treatment with a lowdose second-generation antipsychotic (minimum effective dose within the therapeutic range), adjusted gradually according to response and tolerability and maintained at an adequate dosage for at least for 6–8 weeks before a change is considered. The clinical decision on drug choice is often driven by the sideeffect profile since there is no convincing evidence of differences in clinical efficacy between antipsychotics. For instance, drugs with a propensity towards weight gain and hyperglycaemia may be preferred less for young women or patients from the Indian subcontinent ancestry. Table 3 summarizes the side-effect profile of second-generation antipsychotics. Treatment with antipsychotics should continue for at least 12 months, following which medication may be gradually tapered in those who have made a complete recovery. Many patients with early psychosis are reluctant to take medication. An open and honest discussion offering information about the adverse consequences of untreated psychosis and repeated relapses, clinical benefits versus side-effect concerns and addressing the patient’s or family’s concerns promotes both therapeutic engagement and adherence to medication. It is good practice to discuss with the patient and family the most appropriate medication options, providing comprehensive information

Early recovery phase As the patient’s mental state is stabilized, the treatment plan needs to continue evolving to meet changing needs. There should be regular, structured and documented multidisciplinary reviews of care plans with the patient’s input to update needs and the plan itself. The aim in this phase is to help patients recover their premorbid level of function. Interventions include individual therapy, especially CBT, vocational assessment using principles of individual placement and support (IPS), assessment and management of comorbidity (especially substance misuse and depression, including early identification of hopelessness, pessimism or suicidal ideation), psychoeducation (for patients and carers) and behavioural family interventions. Continuing medication compliance is vital and rates of noncompliance tend to be high – up to 40–60% of the patients.30,31 There are multiple factors involved in poor compliance, including poor medication, subjective evaluation of side effects, insight, depression, social stigma, level of support and understanding provided by relatives and carers, illicit drugs use and poor therapeutic alliance between the patient and the team that provides care.32 Drug misuse, depression, poor medication efficacy and better cognitive performance at baseline are well-known predictors of poor compliance.33 There is some evidence that individualized interventions to identity and deal with these factors can improve the adherence to medication.34 Long-acting depot preparations should be considered early rather than wait for repeated relapses in patients poorly compliant with oral medication. Similarly, clozapine should be considered as soon as treatment resistance becomes obvious, such as after failure of treatment response to two different classes of antipsychotics.

Consolidating recovery and discharge planning As recovery becomes established and enduring, the goals of treatment can shift to maximizing independence in housing, work/training area and leisure activities along with optimizing physical and mental well-being. Relapse-prevention strategies which involve identification of early warning signs are a very useful way of helping patients to gain insight into the illness and learning effective pathways back into care early, should the need arise. A proportion of patients who make a sustained and enduring recovery can be discharged to general practice, especially if they have come off medication. Although it is not clear how long a first-episode case should continue with an EI service, in the UK most EI services manage patients for about 3 years. Following this, patients who experience recurrent relapses, are taking clozapine or have ongoing needs for secondary care can be managed by community teams. A small proportion of chronically ill, severally disabled, high-risk or difficult to engage patients may need to have their care transferred to an assertive outreach team.

Conclusions The treatment provided by FEP services has been revolutionized by the recognition that there is a crucial window of opportunity in the first 2–3 years of the illness that is critical for effective intervention. A combination of service development in the form of specialist EI services, availability of new antipsychotics and evidence for the efficacy of therapies such as CBT in early psychosis have meant that service users and providers can feel hopeful about many first-episode patients living independently in the community. Prodromal interventions are a novel, challenging and exciting area of research and service development, although many ethical and clinical challenges remain. ◆
